DRYING MACARONI.

Specification of Letters Patent.

Application filed December 13, 1907.

Patented April 13, 1909.

Serial No. 406,300.

T 0 all whom it may concern:

Be it known that I, KARL GAMMEL, a citi-. zen of the German Empire, residing at Stuttgart, Wiirtemberg, Germany, have invented certain new and useful Improvements in Drying Macaroni and the Like; and I do hereby dec are the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has for its object improvements in spreading out and drying macaroni and the like.

In 'the ordinary methods the threads of paste emergin in large numbers from-the press were hitherto cau ht in wood boxes, cut therein to the desired lengths, and these wood boxes conveyed with the macaroni to the drying rooms. The macaroni also was laid in several superincumbent layers and was covered with a light cushion. In order to dry the macaroni an air current was then passed through the macaroni ipes themselvesand if ossible through t e small intervals forme by the layering. The drying )rocess thus only commenced with the air ein blown through, for which of course a sary owing to t 1e small section of the pipes.

Now it is evident that the drying in this manner, particularly of thin macaroni with or without very small holes, was not at alluniform and thorough, and therefore the goods were fre uently spoiled.

By ot ier processes the macaroni is conveyed by suitable devices onto pasteboard or cardboard su ports or trays, or spread on theseby han ,after which these pasteboard supports or trays are laid in hurdles or stages, covered with several sheets of paper, and then brought into drying chambers, this drying rocess, which is itself a slow one, being acce erated, if necessary, by means of more The macaroni in the hurdles or stages must be very carefully covered with sheets of pa er in order to avoid any cracking of the good;, because the air in these drying chambers is usually very dry, and also the space required for arranging the hurdles in t is drying process is very great.

The method according to this invention quantities drying to be carried out in an excellent manner, which is in no small degree assisted by the provision of large evaporating surfaces for the moisture contained in the macaroni. For this object also the sections of passage for the air are enlarged and the entire drying operation is simplified. 'l: he latter result is attained by the macaroni being conveyed onto supports of absorbent material, similarly to what was the case in the method hereinbefore mentioned which supports are then stacked one above the other without further difiiculty in the drying chamber, separate, inconvenient, means for covering, and

the like, and also hurdles or stages and the like, being dispensed with.

By this invention the dryin commences from the moment at which t e macaroni is placed on the supports, a portion of the moisture being immediately absorbed by the latter. Now before all the trays of macaroni have been arranged in the drying chamber, the supports wil have absorbed at large part of the moisture and in this way large evaporating surfaces areobtained, so that when air-is passed over them, which maytake place by artificial or natural means, the macaroni is rapidly freed from moisture. By thc'stacking of the macaroni and the sup ports one above the other the former is dried extremely ra idly, as it is done internally and external y simultaneously. The supports may also be provided with longitudinal continuous passages and are then particularly adagtcd for drying thin and long Imacaroni, auc also for that kind of macaroni that has no holes. Of course the macaroni and its supports may also be again arranged in larger quantities in wood frames, but the same feature must always be maintained viz. that the macaroni on its absorbent supports is arranged in superimposed layers.

The method accordin to this invention will now be more particulhrly explained with reference to an arrangement shown as an example in the accompanying drawings, in WhlOllZ Figure 1 is a view of an ap aratus for carrying out my method, while *igs. 2, 3 and 4 are end views of different forms and ways of placing the pasteboard or cardboard supports or trays one above the other.

The macaroni 1) passes out of the press a first onto a rocking frame a and onto supports or trays e of absorbent pasteboard, cardboard or the like, which are placed on this rockin frame a. Preferably these trays e are provided with a bent up edge the height of which corresponds to the diameter of the macaroni. After the macaroni from the press a has been spread on the su ports or trays e the rocking frame is move upward horizontally in known manner, and the macaroni is thereby cut by a slicing device d to the correct lengths. The macaroni b is then brought into a drying apparatus i, the trays 6 being simply stacked one upon the other therein, so that macaroni and trays alternate through the entire pits. The trays 6 may also be provided in the middle with a barf In the form of construction shown in Fig. 4 the cardboard trays e are simply bent up at the ends.

I claim as my invention:

The method of drying macaroni which con sists in passing the macaroni directly from the press in'a single layer on a tray of absorbent material, cutting the macaroni into suitable lengths, and then placing one tray upon another so that the bottom of a superposed tray will contact with the macaroni in 'the tray directly underneath, whereby the layers of macaroni are brought into contact with the material from which the trays are constructed.

In testimony whereof I affix my signature, in presence of two witnesses.
